  • Representing numbers 17, 18, and 19
  • Understanding tens and ones

Learning Objectives

  • Students will be able to count to 19 accurately.
  • Students will be able to identify and write the numbers 17, 18, and 19.
  • Students will be able to decompose the numbers 17, 18, and 19 into tens and ones.

Educator Instructions

  • Introduction (5 mins)
    Start by asking students what numbers they already know. Briefly review counting from 1 to 16. Tell them today we're learning about three new numbers: 17, 18, and 19! Show them the video.
  • Video Viewing (5 mins)
    Play the YouTube video: 'Learn Grade 1 - Maths - Introduction to Numbers 17,18 and 19'. Encourage students to count along with the video.
  • Counting Practice (10 mins)
    Using manipulatives like counters, blocks, or beads, have students practice counting out 17, 18, and 19 objects. Group the objects into one group of ten and the remaining ones to visually represent the tens and ones place value.
  • Writing Numbers (10 mins)
    Have students practice writing the numbers 17, 18, and 19. Write the numbers on the board and say them aloud. Have the students repeat after you. Write the word seventeen, eighteen and nineteen on the board and say each of them aloud. Have the students repeat after you. Provide worksheets with dotted numbers for them to trace and then practice writing on their own. Reinforce the spelling of each number.
  • Tens and Ones Activity (10 mins)
    Use a tens and ones chart. Show students how to place the digits of 17, 18, and 19 in the correct columns. Guide them to understand that '1' in the tens column represents ten and the digit in the ones column represents the number of ones. For instance, for 17, write 1 in the tens column and 7 in the ones column.
  • Wrap Up (5 mins)
    Review what the students learned about the numbers 17, 18 and 19. Briefly recap the main points of the lesson.

Interactive Exercises

  • Number Hunt
    Hide numbers 17, 18, and 19 around the classroom. Have students find them and bring them back to their desks.
  • Counting Game
    Play a class-wide counting game where students take turns counting up to 19. If a student says the wrong number, they are out and the counting restarts at 1.
